How to add browse file button to Windows Form using C#

I want to select a file on the local hard disk when I click a "Browse" button.

I don't have any idea how to use the OpenFileDialog control. Can anyone help me?

These links explain it with examples

private void button1_Click(object sender, EventArgs e)
{
    int size = -1;
    OpenFileDialog openFileDialog1 = new OpenFileDialog();
    DialogResult result = openFileDialog1.ShowDialog(); // Show the dialog.
    if (result == DialogResult.OK) // Test result.
    {
	   string file = openFileDialog1.FileName;
	   try
	   {
	      string text = File.ReadAllText(file);
	      size = text.Length;
	   }
	   catch (IOException)
	   {
	   }
    }
    Console.WriteLine(size); // <-- Shows file size in debugging mode.
    Console.WriteLine(result); // <-- For debugging use.
}

var FD = new System.Windows.Forms.OpenFileDialog();
if (FD.ShowDialog() == System.Windows.Forms.DialogResult.OK) {
    string fileToOpen = FD.FileName;
    
    System.IO.FileInfo File = new System.IO.FileInfo(FD.FileName);

    //OR

    System.IO.StreamReader reader = new System.IO.StreamReader(fileToOpen);
    //etc
}

OpenFileDialog fdlg = new OpenFileDialog();
fdlg.Title = "C# Corner Open File Dialog" ;
fdlg.InitialDirectory = @"c:\" ;
fdlg.Filter = "All files (*.*)|*.*|All files (*.*)|*.*" ;
fdlg.FilterIndex = 2 ;
fdlg.RestoreDirectory = true ;
if(fdlg.ShowDialog() == DialogResult.OK)
{
textBox1.Text = fdlg.FileName ;
}

In this code you can put your address in a text box.
